 Colmena is a simple, stateless NixOS deployment tool modeled after [NixOps](https://github.com/NixOS/nixops) and [Morph](https://github.com/DBCDK/morph), written in Rust.
 It's a thin wrapper over Nix commands like `nix-instantiate` and `nix-copy-closure`, and supports parallel deployment.

 Colmena allows you to upload secret files to nodes that will not be stored in the Nix store.
 It implements a subset of the `deployment.keys` options supported by NixOps.

 Take note that if you use the default path (`/run/keys`), the secret files are only stored in-memory and will not survive reboots.
 To upload your secrets without performing a full deployment, use `colmena upload-keys`.
 
+## Parallelism
+
+Colmena is built from the ground up to support parallel deployments.
+Evaluation, build, and deployment of node configurations can happen at the same time.
+This parallelism can be controlled primarily through two flags:
+
+- `--limit <number>`: Number of hosts to deploy at once in the final step (pushing closures and activating new profiles).
+- `--eval-node-limit <number>`: By default, Colmena will automatically determine the maximum number of nodes to evaluate at the same time according to available RAM. This flag allows you to set the limit to a predetermined value.
